Economic Simplified Boiling Water Reactor
The Economic Simplified Boiling Water Reactor (ESBWR) is a passively safe generation III+ reactor design derived from its predecessor, the Simplified Boiling Water Reactor (SBWR) and from the Advanced Boiling Water Reactor (ABWR). All are designs by GE Hitachi Nuclear Energy (GEH), and are based on previous Boiling Water Reactor designs. Passive safety system The passive nuclear safety systems in an ESBWR operate without using any pumps, which creates increased design safety, integrity, and reliability, while simultaneously reducing overall reactor cost. It also uses natural circulation to drive coolant flow within the reactor pressure vessel (RPV); this results in fewer systems to maintain, and precludes significant BWR casualties such as recirculation line breaks. There are no circulation pumps or associated piping, power supplies, heat exchangers, instrumentation, or controls needed for these systems. ESBWR's passive safety systems include a combination of three systems that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grand Gulf Nuclear Generating Station
Grand Gulf Nuclear Station is a nuclear power station with one operational GE BWR reactor (General Electric boiling water reactor). It lies on a site near Port Gibson, Mississippi. The site is wooded and contains two lakes. The plant has a 520-foot natural draft cooling tower. As of January 2023, the plant employs 675 people. Grand Gulf's reactor is the most powerful in the US and the 7th most powerful in the world, with a core power of 4408 MWth yielding a nominal gross electrical output of 1443 MWe. Grand Gulf is operated by Entergy, which also owns 90% of the station through their subsidiary, System Energy Resources Inc. The other 10% is owned by Cooperative Energy. Units 2 and 3 Adjacent to the operating Grand Gulf station, is an unfinished concrete structure that was to be the containment for Unit 2, a twin to the existing Unit 1. In December 1979, staggered by construction cost, Entergy (then called Middle South Utilities) stopped work on Unit 2. On September 22 ...

VVER-TOI
The VVER-TOI or WWER-TOI (russian: text=Водо-водяной энергетический реактор типовой оптимизированный информатизированный, translit=Vodo-Vodyanoi Energetichesky Reactor Tipovoi Optimizirovanniy Informatizirovanniy, lit= Water-Water Energy Reactor Universal Optimized Digital ) is a generation III+ nuclear power reactor based on VVER technology developed by Rosatom. The VVER-TOI design is intended to improve the competitiveness of Russian VVER technology in international markets. It would use VVER-1300/510 water pressurized reactors constructed to meet modern nuclear and radiation safety requirements. The VVER-TOI project is developed on the basis of the design documents worked out for AES-2006, considering the experience gained in development of projects based on VVER technology both in Russia and abroad, such as Novovoronezh Nuclear Power Plant II. The first VVER-TOI will be unit 1 of the Kursk II Nuclear P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Pressurized Water Reactor
The Mitsubishi advanced pressurized water reactor (APWR) is a generation III nuclear reactor design developed by Mitsubishi Heavy Industries (MHI) based on pressurized water reactor technology. It features several design enhancements including a neutron reflector, improved efficiency and improved safety systems. It has safety features advanced over the last generation, including a combination of passive and active systems. None are currently under construction. History The standard APWR is going through the licensing process in Japan and two (of 1538 MWe) are being constructed at the Tsuruga plant. The next APWR+ will be of a 1700 MWe power and have full MOX core abilities. The US-APWR was developed by MHI to modify their APWR design to comply with US regulations. TXU selected the US-APWR for use at multiple sites, including the Comanche Peak Nuclear Generating Station. However, in 2013, Mitsubishi slowed U.S. certification work, and the application to build two units at Coman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Pressurized Reactor
The EPR is a Generation III reactor, third generation pressurised water reactor design. It has been designed and developed mainly by Framatome (part of Areva between 2001 and 2017) and Électricité de France (EDF) in France, and Siemens in Germany. In Europe this reactor design was called European Pressurised Reactor, and the internationalised name was Evolutionary Power Reactor, but it is now simply named EPR. The first operational EPR unit was China's Taishan Nuclear Power Plant, Taishan 1, which started commercial operation in December 2018. Taishan 2 started commercial operation in September 2019. European units have been so far plagued with prolonged construction delays and substantial cost overruns. The first EPR unit to start construction, at Olkiluoto Nuclear Power Plant#Unit 3, Olkiluoto in Finland, achieved Criticality (status), criticality in December 2021. It is expected to begin commercial operation after February 2023, a delay of thirteen years. The secon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power 2010 Program
The "Nuclear Power 2010 Program" was launched in 2002 by President George W. Bush in 2002, 13 months after the beginning of his presidency, in order to restart orders for nuclear power reactors in the U.S. by providing subsidies for a handful of Generation III+ demonstration plants. The expectation was that these plants would come online by 2010, but it was not met. In March 2017, the leading nuclear-plant maker, Westinghouse Electric Company, filed for bankruptcy due to losing over $9 billion in construction losses from working on two nuclear plants. This loss was partly caused by safety concerns due to the Fukushima disaster, Germany's Energiewende, the growth of solar and wind power, and low natural gas prices. Overview The "Nuclear Power 2010 Program" was unveiled by the U.S. Secretary of Energy Spencer Abraham on February 14, 2002 as one means towards addressing the expected need for new power plants. The program was a joint government/industry cost-shared effort to ident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generation III Reactor
Generation III reactors, or Gen III reactors, are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design. These include improved fuel technology, higher thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), and standardized designs intended to reduce maintenance and capital costs. They are promoted by the Generation IV International Forum (GIF). The first Generation III reactors to begin operation were Kashiwazaki 6 and 7 advanced boiling water reactors (ABWRs) in 1996 and 1997. Since 2012, both have been shut down due to security concerns. Due to the prolonged period of stagnation in the construction of new reactors and the continued (albeit declining) popularity of Generation II/II+ designs in new construction, relatively few third generation reactors have been built. Overview The older Gen II reactors comprise the vast majority of current nuclear reactors. Gen III re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economics Of Nuclear Power Plants
Nuclear power construction costs have varied significantly across the world and in time. Large and rapid increases in cost occurred during the 1970s, especially in the United States. Recent cost trends in countries such as Japan and Korea have been very different, including periods of stability and decline in costs. New nuclear power plants typically have high capital expenditure for building plants. Fuel, operational, and maintenance costs are relatively small components of the total cost. The long service life and high capacity factor of nuclear power plants allow sufficient funds for ultimate plant decommissioning and waste storage and management to be accumulated, with little impact on the price per unit of electricity generated. Additionally, measures to mitigate climate change such as a carbon tax or carbon emissions trading, favor the economics of nuclear power over fossil fuel power. Nuclear power is cost competitive with renewable generation when capital cost is in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
